Abstract
We reported a case of gastric schwannoma which was encounterd at operation for early gastric cancer. The patient was a 59-year-old man with a chief complaint of abdominal distention. The endoscopic examination revealed a superficial elevated lesion in the posterior wall of the antrum and the diagnosis of gastric cancer (tubular adenocarcinoma) was made with the biopsies. Subtotal gastrectomy was performed. At the operation, in addition to the carcinoma, a subserosal mass (4×3×3cm) was also found in the lesser curvature of the middle corpus. Histologically, palisading arrangement of spindle shaped cells was significant. With Azan staining and silver impregnation, the tumor cells were considered to be non-muscular origin and diagnosis of schwannoma was made.
